7 Claims. (01. 229-30) -in which the sides and bottom are integral,being formed of a properly shaped and folded cardboard blank. Ireenforce the perimeter of the open end of the carton by means of ametallic reenforcing band so united with the sides of the carton that itwill not be exposed to contact with the contents of the carton norvisible so as to become unsightly because of corrosion. This reenforcingband is so applied to the perimeter of the carton that it will reenforcethe latter so that it will maintain its proper form.

One form which the invention may assume is exemplified in the followingdescription and illustrated by way of example in the accompanyingdrawing, in which:

Fig. 1 is a perspective view of a completed carton constructed inaccordance with my present invention. 7

.Fig. 2 is an illustration of the cardboard blank by forming the bottomand sides of-the carton.

Fig. 3 is a perspective view of the reenforcing band prior to its beingformed and applied to the carton.

Fig. 4 is a perspective view of the carton shown inverted and in theprocess of manufacture.

Figs. 5, 6, 7, and 8 are fragmentary views in section through theperimeter of the carton showing the steps of applying the reenforcingband thereto.

Referring more particularly to the accompanying drawing, l indicates acarton formed principally of cardboard or like sheet material. Thiscarton is formed of an imperforate bottom II and side walls l2. Theupper end of the carton is open as illustrated. It should be pointed outthat the area of the bottom of the carton is slightly less than its openupper end so that the cartons will nest properly so that they may bepacked and shipped economically.

The carton is formed from a blank Id of cardboard or like sheetmaterial. This blank is cruciform in plan and comprises a square centralsection l5 forming the bottom of the carton and integral with which aresections l6 forming the sides of the carton. The blank may be scoredalong the broken lines I! to enable the'sections It to be foldedrelative to the section IE to form the carton; The sections I6 may bescored along the broken lines l8 and I9 for the reception of 5 a.reenforcing band as will be hereinafter described. a

By reference to the drawing, it will be noted that the perimeter of theopen upper end of the carton is reenforced by means of a circumscrib- 10ing reenforcing band 20. This band is constructed as illustrated in Fig.3 .where it will be notedthat it consists of a strip of metal of anglecross section. At intervals one toe of the angle is formed with cut-awayportions 2|. These cutaway portions occur at the corners of the carton.To apply the band to the carton it -is bent into the form of a squareagreeing in dimensions with the upper end of the carton with the cornerbends occurring centrally of the cut-away portions 2|. 1 The band isthen applied to the carton with the uncut flange adjacent the outersurface of the carton and with the cut flange uppermost and extendinglaterally outward from the sides of the carton. The band is positionedwith its upper edge in alignment with the scoring l8 of the sidesections l6 of the blank, as shown in Fig. 5, and the upper ends of theside Walls of the carton are then bent laterally outward over thelaterally outward extending flange of the reenforcing band, as shown inFig. 6. .At this time the scoring l9 of the sides of the carton willalign with the outer edge of the laterally and Qua wardly directedflange of the reenforcing band. The extremities of the sides are thenfolded over the laterally projecting flange of the reenforcing band, asillustrated in Fig. 7. After this has been accomplished, the laterallyprojecting por- I tion of the sides of the carton together wtih thelaterally extending flange of the reenforcing band are folded againstthe sides of the carton, as illustrated in Fig. 8. As the reenforcingband will retain this position, the folded extremities of the cartonwill be properly clamped in place between the toes of the band.

It will be seen that when the carton is completed, the reenforcing band29 will be entirely concealed so that it will not become unsightly dueto corrosion and will not .come in contact with the contents of thecarton. However, the provision of the'reenforcing band wil give thecarton sufficient rigidity so that it will retain its proper form. 1

In practicing my invention, the carton is constructedby forming theblank M of cardboard or similar sheet material. If the carton is ofcomparatively heavy material, it may be scored along the lines l1, l8,and I9. However, when using certain sheet materials, such scoring willbe unnecessary. The reenforcing band20is then formed and bent into arectangular shape with the comer bends occurring centrally of thecut-away portions 2|. When properly bent, the reenforcing band willoutline asquare agreeing in dimensions with the perimeter of the cartonat its upper end. The side sections of the blank are then foldedrelative to the bottom section and the reenforcing band is appliedthereto as illustrated in Fig. 5. The extremities of the side sectionsare then bent laterally outward as illustrated in Fig. 6, the bendoccurring along the scoring lines l8 in register with the upper surfaceof the reenforcing band 20. The extreme ends of the side sections l6 arethen bent over the laterally projecting toe of the reenforcing band 20,as illustrated in Fig. '7, and thereafter the laterally projectingportions of the side sections l6 and the reenforcing band 20 are foldedagainst the exterior surfaces of the side sections l6, as illustrated inFig. 8, firmly clamping the extremities of the side sections IS infolded position.

In the manufacture of the carton the fcregoing operations may be eitherperformed manually or by means of machines. It will be noted that thereenforcing band is so covered by the cardboard material of which thecarton is principally composed that it cannot come in contact with thecontents of the carton. Likewise, its surfaces will not be exposed tothe eye so that in the event 1 of any corrosion of the reenforcing band,the carton will not become unsightly.

It will be noticed also that the carton is con- 'structed so that itsbottom area will be less than its top area, thus enabling the cartons tobe nested: when constructed so that the packing and shipping costs willbe minimized. 7

From the foregoing it is obvious that I have provided a carton which isdurable in construction and which will be comparatively inexpensive tomanufacture and while I have shown the preferred form of my invention,it is to be understood that various changes may be made in itsconstruction by those skilled in the art without departing from thespirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

l. A carton formed of a cardboard blank folded to form a bottom andsides upturned therefrom,

a reenforcing member of angular cross section circumscribing the-sidesat the upper end of the carton, the upper extremity of the sides beingpassed around said member and said member being folded upon itself togrip the sides and be concealed thereby. I

2. A carton formed of a cardboard blank folded to form a bottom andsides upturned therefrom, a metallic reenforcing band arrangedexteriorly of the sides and circumscribing the carton at the upper endthereof, the upper extremity of the sides and said reenforcing bandbeing interfolded to form a reenforced edge comprising two thicknessesof metal and three thicknesses of cardboard.

of a cardboard blank shaped and folded to form a bottom and sidesupstanding from the bottom, a metallic reenforcing band arranged at theexterior of the sides at the upper end of the carton and completelycircumscribing the carton, said band having a portion lying parallel toand in contact 'with the exterior surface of the sides, said reenforcingband having portions over which the extremity of the sides may befolded, said latter portions being folded against the former portions tosecure the extremities of the sides folded thereover.

5. In a cardboard carton, a reinforcing memmember folded over the edgeof the cardboard to strengthen the same, said cardboard being foldedadjacent its edge to surround and conceal the metallic member.

6. In a cardboard carton, a reinforced edge comprising a metal stripfolded to grip the cardboard at, its edge and interfolded with thecardboard to be concealed thereby.

7. In a cardboard carton, a reinforced edge comprising a metallic memberso interfolded with the cardboard that it will cover and protect theedge thereof and be surrounded and concealed thereby.
